### I need to know how much stone in tons I need to fill 8.5 acre at 1.5 ft depth

Stone is approximated at about 2700 lbs. per cu. yd.
An acre is 43560 sq. ft.
8.5 acres is 370260 sq. ft.
There 9 sq.ft. per sq. yd., thus there are 41140 sq. yds. in 8.5 acres.
A cubic yard is 3 feet by 3 feet by 3 feet (LxWxH).
Since you are only going to be at 1.5 feet, each square yard is equal to 1/2 cubic yard, so to figure the cubic yards divide sq.yds. by 2, thus you get 20570 cu. yds. of stone.

20570 x 2700 = 55539000 pounds. Divide by 2000 to get tons:
55539000/2000 = 27769.5 tons.

### Bought the new version of the jacuzzi1.5hpLRC motor. The hook up to the pump is on top instead of the side. Is there tubing we can use to connect the two?

Unless there is a proprietary hook-up ( i coundnt find one) the best thing would be to plumb it in with pvc. They do have Flex PVC pipe but I've never used or heard anything about it so use at your own risk.

### Convert 30pounds per sq.foot to pounds per cubic foot(concrete=150#/cubic foot at 1in. thick conc. slab).

These are not the same, so cannot be directly converted.

Pounds per sq ft is a measure of pressure, while lbs / cu ft is a measure of density, weight per unit volume.

I think maybe what you are doing here is converting the weight of concrete in a 1" slab, where a sq ft would contain

1 x 1 x 1/12 = .0833 cu ft

The figure of 150 lb/ cu ft is correct for the average density of concrete, so the above slab would have

1/12 x 150 = 12.5 lbs/sq ft at 1" thickness

BTW that is a thin slab of concrete, insufficient even for a light-duty pathway. If you are referring to a screed for tiling or similar, that is cement.

### Why does Grundfus bell pump dry runs won't turn off?

If you have a switch of some sort to tell the pump the house needs water, look there first.

### Republic EZ broadcast spreader...what number to use when lining up the mark to calibrate the spreader...lost the instruction book

1. If you don't already know the square footage of your lawn, please walk off or measure, multiplying the length by width. For example, my lawn is 100 ft wide by 100 ft long; this equals 10,000 sq. ft.
2. Use this figure (30,000 sq ft) to determine how much fertilizer, insecticide, fungicide,apply etc., to purchase and apply.
3. To calibrate the spreader for applying your product at the correct rate, first weigh and hold out an amount of product to cover a pre-determined test area; for example, enough for a 200 sq ft space.
4. Because most lawn fertilizers are packaged to cover areas in 1000 sq ft increments, it's easy to figure how many 1,000 sq ft applications you need for your lawn.
5. Set your spreader to 3 and measure 1/5 of the recommended application on your product, to cover a 200 sq ft area.
7. If there is product remaining in the hopper after walking this 200 sq ft area, increase the setting number and move to another test area, repeat steps 5 and 6.
8. If there wasn't enough product to cover the test area, back the number down, move to another test area, and repeat steps 5 and 6, until you finish with product and lawn test area at the same time.
9. Remember to never leave product in your hopper because many chemicals are corrosive and can destroy the moving parts, making the spreader inoperable.

I hope this helps!

### 8 inch woofer blown need specs...OHM, Impedence and wattage

John,
Checkout JL Audio's 8" subs I'll leave specs at the bottom, if you want to look around for something cheaper check out this install I did on a Jaguar X-Type. The sub here is a good example of a free air application and you can look for a sub with the same features. Keep in mind however this setup is using a high power Coustic 10" sub and you only need to handle the stock amp- 25 watts. So you may not need such a beefy sub, but something close would be good. If your sub uses a small enclosure go with something like the JL listed below. Good luck and let me know if you need anything else. -Dynami
